Rack



Nov. 10, 1 931. P. H. CHASE RACK Filed June 4, 1928 Patented Nov. 10, 1931 UNITED STATES- PATENT orrics Application filed Jane 4,

This invention relates to racks and with regard to certain more specific features to ks for insulators and like fi units; the provision of a reenforcement for the base and legs of such interchangeable rack; the rovision of a decl which increases II at it may withstand greater vertical loads. 1

her objects will be'in part pointed out hereina ter.

e invention accordingly comprises the parts which will be exemplified in the structures hereinafter described, and the scop application of which will be indicated in the following clauses.

In the accompanying drawings in which are illustrated various embodiments of the invention;

Fig. l is a side elevation showing one form of assembly of the rack;

' ig. 2 is a side elevation of Fig. 1; ig. Bis a plan view of Fig. 1;

Figs. 4, 5 and 6 are views similar to Figs. '1, 2 and 3 showing'a modified form of the evice;

Figs. 7 and 8 are views similar and 5 illustrating the omission of certain fastening tongues and bolts; and

Figs. 9 and 10, taken together illustrate a juxtaposed relationship between certain rack m units and a locking base.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

eferring now more particularly to Figs.

5 1, 2 and 3, there' is illustrated a group of three U-shaped interchangeable rack units 1 which have bee n assembled by sliding the toFigsA 1928. Serial No. 282,577.

with holes 9 formed in the said upper legs 5. of holding the rack unlts 1 assembled is shown in Figs. 4 to 6, wherein bolt-and-nut combinations 11 are used.

In all th difications herein described 55 units together and also acts as a spindle to support spool type insulators, also not shown, said insulators In the'preferred embodiment of m invention, the 1 provided with aligned notches 15 on either side, saidnotches eing formed near the junctions of the legs with backs 17 of said U-shaped units (Figs. 9 and base or looking channel 18 with ears 20, f d to engage with the notches is formed so as to be d so. may be apout vided with holes 19 which line up with corresponding holes in the backs 17 of the rack units, as desired, irrespective of the length of the legs of the rack t will be noted that in Figs. 1 to 3, the

understood that the channel 17 is made of such depth so as to accommodate the particular type of rack units to which it is to be applied.

Figs. 7 and 8 illustrate the use of the lock g channel 18 with a plurality of rack units 00 'said notches.

1 which are not fastenedby bolting or tonguing together adjacent legs thereof. This method of construction may be employed where no assemblies of rack units in the field without the base 18 are required. Figs. 9 and 10 show the relationship of parts prior to the application of the locking channel over the backs of the rack units. It is to be understood that the widths of the backs of the rack units are slightly greater than the width of the channel in the locking channel piece 18, thereby affording a springing action when the channel piece is driven on so as to hold the pieces together.

In view of the above, it is believed that the various features of this invention will be clear without further elaboration, and it will be seen that with the apparatus herein described, the several objects of the invention are achieved and other advantages results attained.

As many changes could be made in carrying out the above construction without departing from the scope of the invention, it is intended that matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim:

A rack for insulators and the like comprising insulator supporting units having back portions and legs extending therefrom, notches in the legs near said back portions and a reenforcing channel surrounding at least part of said back portions and engaging In testimony whereof, I have signed my name to this specification this 31st day of May, 1928.
